Etymology: Probarbus: Greek, pro = first, in front of + Latin, barbus = barbel (Ref. 45335).

Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; potamodromous (Ref. 51243). Tropical
Asia: endemic to the Mekong.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 150 cm SL male/unsexed; (Ref. 30857); max. published weight: 70.0 kg (Ref. 10431)
soft rays: 8;
Vertebrae: 40 - 41. Differs from the two other species of Probarbus in having slightly smaller (and more numerous) scales, scale row between dorsal fin origin and lateral line scale row 6; six instead of only five stripes on body above lateral line; lips greatly enlarged; barbels reduced in length, sometimes absent; and slightly more numerous vertebrae. Posterior margin of lower lip entirely free from side to side.
Occurs in large upland rivers. Feeds on benthic organisms and insect larvae (Ref. 58784). Undergoes upstream movement for spawning (Ref. 58784). Little is known about this species due to past confusion with P. jullieni. Apparently migrates together with P. jullieni and has been decimated by the intensive gillnet fishery directed at that species just above the Lee Pee Waterfalls in southern Laos (Ref. 10431). However, further investigation is needed to find out whether it shares the same spawning grounds and times (Ref. 10431).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Very high vulnerability (90 of 100).
